Background And Objective:
To determine effect of surgeon experience on outcomes of LASIK.
Patients And Methods:
Retrospective case series of myopic femtosecond LASIK performed by residents and fellows compared to an attending surgeon, with mean follow-up of 6.6 months.
Results:
Seventy-two eyes (38 patients) had LASIK performed by a trainee and 157 eyes (83 patients) by an attending surgeon. There were no statistically significant preoperative differences. The attending surgeon had lower mean flap thickness (P = .0001), but ablation depth and residual stromal bed were similar. Postoperative uncorrected distance visual acuity was significantly better in the experienced surgeon group on the first postoperative day (P = .0203). Postoperative findings of microstriae (P < .0001) and interface debris (P = .0034) were more common with trainee-performed LASIK.
Conclusion:
Visual outcomes are excellent after femtosecond LASIK performed by trainees and experienced surgeons. Early postoperative complications are more common in trainee-performed LASIK, but are not visually significant. Resident and fellow LASIK surgical training with a comprehensive refractive curriculum under the guidance of an experienced surgeon is safe and appropriate.

Guidelines for Writing Outcome
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
